Facile synthesis of MnO2nanoparticles for the removal of cationic dye Pushparaj Gowthami, Subramanian Rohith Susi Kumar, Giriraj Kalaiarasi, Arumugam Kosiha, Lakshminarayanan Srimathi Priya, Mohamed H. Mahmoud, Hassan Fouad, Abuzar Ansari Zeitschrift Fur Physikalische Chemie, 2024 MnO2 NPs were synthesized from Delonix elata leaves extract act as a capping and reducing agent by green synthesis process. The synthesized MnO2 NPs were characterized by different spectroscopic techniques such as IR, UV-Vis, SEM and XRD analyses. The UV spectrum of synthesized MnO2 NPs revealed optical properties at 340 nm. The XRD pattern of MnO2 NPs exhibited the crystallite size to be in the range of 20 nm and shows the amorphous structure. The morphological geographies of MnO2 NPs are spherical and faintly agglomerated. The FT-IR spectrum of MnO2 NPs spectacles stretching vibration of Mn–O at 510 cm−1 confirmed the formation of MnO2 NPs. MnO2 is superior photo degradation for methylene blue which is extant in the textile industries and it has an unlimited potential application in wastewater treatment.
Biosynthesis of Co3O4 nanomedicine by using Mollugo oppositifolia L. aqueous leaf extract and its antimicrobial, mosquito larvicidal activities P. Gowthami, A. Kosiha, S. Meenakshi, G. Boopathy, A. G. Ramu, Dongjin Choi Scientific Reports, 2023 Nanotechnology is a relatively revolutionary area that generates day-to-day advancement. It makes a significant impact on our daily life. For example, in parasitology, catalysis and cosmetics, nanoparticles possess distinctive possessions that make it possible for them in a broad range of areas. We utilized Mollugo oppositifolia L. aqueous leaf extract assisted chemical reduction method to synthesize Co3O4 nanoparticles. Biosynthesized Co3O4 Nps were confirmed via UV–Vis spectroscopy, scanning electron microscope, X-ray diffraction, EDX, Fourier-transform infrared, and HR-TEM analysis. The crystallite size from XRD studies revealed around 22.7 nm. The biosynthesized Co3O4 nanoparticle was further assessed for mosquito larvicidal activity against south-urban mosquito larvae Culex quinquefasciatus, and antimicrobial activities. The synthesized Co3O4 particle (2) displayed significant larvicidal activity towards mosquito larvae Culex quinquefasciatus with the LD50 value of 34.96 µg/mL than aqueous plant extract (1) and control Permethrin with the LD50 value of 82.41 and 72.44 µg/mL. When compared to the standard antibacterial treatment, Ciprofloxacin, the Co3O4 nanoparticle (2) produced demonstrates significantly enhanced antibacterial action against the pathogens E. coli and B. cereus. The MIC for Co3O4 nanoparticles 2 against C. albicans was under 1 μg/mL, which was much lower than the MIC for the control drug, clotrimale, which was 2 µg per milliliter. Co3O4 nanoparticles 2, with a MIC of 2 μg/mL, has much higher antifungal activity than clotrimale, whose MIC is 4 μg/mL, against M. audouinii.
